E16-34: Practical Introduction to Titration Method Development

HALF-Day Course 
Wednesday, November 16, 8:30am – 12:30pm

Frederick Fiddler, Methrom USA, Riverview, FL

Titration is widely used for quantitative chemical analysis in the pharmaceutical and personal care industries. Titrations provide vital information for raw material content, active pharmaceutical ingredients (API), intermediates, and final product testing. This Short Course categorizes titrations broadly as; Potentiometric, Karl Fischer and Colorimetric titrations. An introduction is provided to these major categories of titration with an emphasis on electrode selection, method development, troubleshooting, and parameter optimization using case studies. This course will focus on best practices for obtaining accurate and precise titration results by giving an in-depth understanding of the core principles of the aforementioned types of titrations and their optimization. The principles and concepts covered in this course will provide attendees with the ability to optimize existing titrations, apply new approaches where needed and consistently provide titration data that is accurate and precise.

This half-day course is ideal for lab chemists, quality control personnel, analytical chemists involved in method development and validation, and managers interested in an in-depth understanding of titration applications and optimization. EAS attendees who are already using automated titrators or are planning to purchase automated titration instruments in the near future will find this class beneficial.
